Observing the Sun through the kitchen window

The Sun with spots as observed on Sat, 16th Jan. 2010 at 265mm focal length:
Digital zoomed (at effectively 530mm focal length):
The photo above has been shot through the closed kitchen window (!) with a tiny Tak FS-60C (@ f/30) telescope and a special Baader Astrosolar filter. The sky was partially cloudy preventing to reach the maximum resolution of my telescope. Even so some sunspots are clearly visible. Sunspots are "cold" areas with strong magnetism on the Sun surface. Caution: Do not attempt to observe the Sun without using special solar filters. For further information, please contact your telescope dealer.
